I think the only reason Joyner was franchised is because of how bad the secondary was at the end of the season.
Les Snead getting Peters,Talib,Shields has been huge !!
My thoughts at the time the Rams tagged LJ was due to many elements that were going on @ CB not Safety.
Wade had his best CB Trumaine Johnson already heading into FA'cy his other starting outside corner Webster was badly damaged with two surgeries to his shoulder & Achilles that was going to effect his play this season. Then the top reserve corner NRC was also heading into FA'cy. The Nickle safety & part time start Cody Davis was also heading into FA'cy. The situation @ corner was dire state. Fact is LJ was this teams
Nickle corner or part time starter @ corner since 2014.
Snead & McVay got busy in the early off season & made some best trades in this Ram franchize this last decade in trading for two all pro corners in Peters & Talib & then signs the best UFA Nickle corner NRC & sign's ex all pro corner Sam Shields..
LJ who can play & start at any of the secondary positions now can go into this season starting @ his best NFL position @ safety. Chance is LJ will benefit greatly this season from playing with so many great DB's playing together on one team. LJ stands a good chance to have an all pro 2018 season & will set him up to be the top safety heading into Free Agency in March of 2019. Yes its highly probable that this will be LJ 's last season as a Ram.
